The amateur limit is 1000 Watts. Personally I ran 800+ Watts on the 2
metre band in the late 1980s for my EME (moonbounce) station. All
analog, single long-boom Yagi. I used a 2M downconverter and listened
on my 10M receiver as it was way more sensitive than my 2M rig.
Over about a year's operation I heard about 10 stations via EME and
worked only 2. Still, that was a very good operational record for a
single Yagi station of the era.
Possibly relevant to Marcus' and others' warnings, my power amplifier
did EXPLODE on one occasion due to dried-out filter capacitors. Big
fireball, and little bits of paper blown right through the amplifier
case and all over the room. It was spectacular :=/
My wife tells the story very well: she was in the kitchen and heard this
big "BOOM". She called upstairs "Is everything alright?" and I calmly
replied "No problem. Could you bring the fire extinguisher up here please?"
Fortunately no fire, and I replaced the filter capacitors. The
amplifier was fine - a good bonus, as I had borrowed it from a research
lab at a local university for a couple of weeks.
With the new weak signal DSP techniques, I hear that 100 Watts and a
single Yagi will get you many contacts, although the data rate will be
very low. Still, it works and that is amazing!
I think Daniel was just asking if these German amplifiers are good
quality. I hear that they are, and that they work very well, although I
have never used or seen one in person. I hear they stand behind their
gear, and will also do custom designs.

I'm on Marcus' side with that output power, that's a scary high
output. I start to sweat at 10W... :)
Heh, I connected a USRP to a 20KW PA once. Sweating was only one of
several things done in anticipation :)
